The interface to the `os_vif` library is very simple. To begin using the
|
|
library, first call the `os_vif.initialize()` function. This will load all
|
|
installed plugins and register the object model:
|
|
|
|
.. code-block:: python
|
|
|
|
import os_vif
|
|
|
|
os_vif.initialize()
|
|
|
|
Once the `os_vif` library is initialized, there are only two other library
|
|
functions: `os_vif.plug()` and `os_vif.unplug()`. Both methods accept a single
|
|
argument of type `os_vif.objects.VIF`:
|
|
|
|
.. code-block:: python
|
|
|
|
import uuid
|
|
|
|
from nova import objects as nova_objects
|
|
from os_vif import exception as vif_exc
|
|
from os_vif import objects as vif_objects
|
|
from os_vif import vnic_types
|
|
|
|
instance_uuid = 'd7a730ca-3c28-49c3-8f26-4662b909fe8a'
|
|
instance = nova_objects.Instance.get_by_uuid(instance_uuid)
|
|
instance_info = vif_objects.InstanceInfo(
|
|
uuid=instance.uuid,
|
|
name=instance.name,
|
|
project_id=instance.project_id)
|
|
|
|
subnet = vif_objects.Subnet(cidr='192.168.1.0/24')
|
|
subnets = vif_objects.SubnetList([subnet])
|
|
network = vif_objects.Network(label='tenantnet',
|
|
subnets=subnets,
|
|
multi_host=False,
|
|
should_provide_vlan=False,
|
|
should_provide_bridge=False)
|
|
|
|
vif_uuid = uuid.uuid4()
|
|
vif = vif_objects.VIFVHostUser(id=vif_uuid,
|
|
address=None,
|
|
network=network,
|
|
plugin='vhostuser',
|
|
path='/path/to/socket',
|
|
mode=vif_objects.fields.VIFVHostUserMode.SERVER)
|
|
|
|
# Now do the actual plug operations to connect the VIF to
|
|
# the backing network interface.
|
|
try:
|
|
os_vif.plug(vif, instance_info)
|
|
except vif_exc.PlugException as err:
|
|
# Handle the failure...
|
|
|
|
# If you are removing a virtual machine and its interfaces,
|
|
# you would use the unplug() operation:
|
|
try:
|
|
os_vif.unplug(vif, instance_info)
|
|
except vif_exc.UnplugException as err:
|
|
# Handle the failure...
